enables you to create a library containing just one

file, if this file is located on the Internet and can be accessed over HTTP. If you refer to a JavaScript library that is not yet available locally, but is available online, use the
Download libraryintention action:
The library will be placed to the user home directory, and will appear in the list of configured libraries in the

page of the
Settings
dialog.
